As a work-around, If you add -fno-blocks to the CFLAGS, it will build cleanly.
The problem is that apple's gcc ships with some custom patches to support 
lexical closures in C, C++, and Objective-C.

As an aside, building with -std=c99 (which also disables blocks), causes the 
code to emit hundreds of warnings and seems to enable a version of strcpy that 
acc can't handle due to a (I suspect) __restrict keyword which means that at 
present you can't easily use this with C99 code.
